Which modality is listed for wound healing?

• A. Ultrasound
• B. Cryotherapy
• C. Manual lymphatic drainage
• D. Microcurrent

Answer: (D)

Wound healing relies on cellular activities such as epithelialization, collagen synthesis, and angiogenesis. Microcurrent delivers very small electrical currents that resemble the body’s own bioelectric signals, which can boost ATP production and core cellular activity at the wound bed. This electrical stimulation helps drive fibroblast activity, collagen deposition, and cell migration, while also improving local blood flow and reducing edema. Because of these targeted effects on the healing process, microcurrent is the modality most closely associated with actively promoting wound repair. Ultrasound can aid tissue healing through thermal and mechanical effects, but it isn’t as consistently framed as a wound-healing modality in this context. Manual lymph drainage focuses on reducing edema rather than directly stimulating tissue repair. Cryotherapy helps with acute inflammation and pain control, not primarily with wound healing.
